A question: why do you not have a pr.gro? It should been output by the mdrun of pr.tpr?
Anyway, yes you should be able to use -c pr.tpr. However you need to make sure to use -t pr.trr or -t pr.cpt to ensure it uses the coordinates and velocities from the end of the equilibration run. Even if you use -c pr.gro, it is a good idea to use -t to ensure that it uses the full-precision coordinates and velocities from the previous run. The -c .gro/.tpr are at a minimum necessary for grompp to put atom names into the new .tpr file that it generates.
